Introducing nitrogen into the four-neck flask, after the internal temperature rises to 80 ℃, dropwise adding the monomer and the initiator for 1.5 hours, then keeping the temperature at 80 ℃ for reaction for 6.5 hours, and cooling to obtain the acrylic acid ester pressure-sensitive adhesive grafted and modified by the phosphorus-free monomer and the cyclic monomer, which is marked as pressure-sensitive adhesive P1. The P1 sample was coated on a 25 μm-PET film, and a dry gel was coated 100 μm. As the phosphorus-containing monomer was not grafted, the flame retardant rating test thereof is shown in Table 1, and the flame retardant property was not exhibited by complete combustion.
Comparative example 2
In accordance with the process of comparative example 1, the product was designated pressure sensitive adhesive P2. Only the phosphorus-containing monomer is grafted and introduced, the flame retardance of the polymerization product is improved compared with that of comparative example 1, the VTM-2 grade can be achieved, but the molecular weight and the monomer conversion rate are obviously reduced.
Example 1
The synthesis device is a four-neck flask provided with 1 set of mechanical stirrer, 1 set of condensing reflux device, 2 constant-pressure dropping funnels and 1 set of nitrogen device.
Into a four-necked flask, the amount of the bottom monomer of the formulation of Table 1, 115 g of toluene and 335 g of ethyl acetate were charged, and 155 g of ethyl acetate and the mixture of the grafting monomer and the initiator of the formulation of Table 1 were charged into a constant pressure dropping funnel. Introducing nitrogen into the four-neck flask, after the internal temperature rises to 80 ℃, dropwise adding the monomer and the initiator for 1.5 hours, then keeping the temperature at 80 ℃ for reaction for 6.5 hours, and cooling to obtain the acrylic pressure-sensitive adhesive grafted and modified by the phosphorus-containing monomer and the cyclic monomer, wherein the pressure-sensitive adhesive is denoted as P3.
The P3 molecular weight was slightly reduced, but the flame retardant rating was significantly increased, reaching the VTM-1 rating, as compared to the product of comparative example 1. Compared with the product of comparative example 2, the molecular weight and the flame retardant grade of P3 are both improved.
Example 2
The same synthesis procedure as in example 1, reduced initiator usage, higher molecular weight polymer was obtained, the pressure sensitive adhesive was designated as P4, and the same flame retardant rating was maintained.
Example 3
The same synthesis process as in example 1, the same initiator amount as in example 2, the same phosphorus monomer amount, and cooling to obtain the acrylic pressure sensitive adhesive grafted and modified by both phosphorus monomer and cyclic monomer, wherein the pressure sensitive adhesive is designated as P5.
Example 4

curing agent: 0.5% -3%;
the rest is ethyl acetate.

The pressure-sensitive adhesive P1 used was weighed in accordance with the proportions of Table 2, and after stirring uniformly, the components were coated on a 25 μm-PET film, and a dry adhesive of 100 μm was applied for measuring the flame retardance. The adhesive was coated on a 25 μm-PET film, and a dry adhesive of 25 μm was coated for measuring various properties of the pressure-sensitive adhesive. Comparative example 3 the flame retardant test result was complete combustion since no flame retardant was added.
Comparative examples 4 to 5
The pressure-sensitive adhesive is P1, and flame retardants with different amounts are added on the basis of the P1 pressure-sensitive adhesive, so that the flame retardance is improved along with the addition amount of the flame retardants, but the performance of the pressure-sensitive adhesive is obviously reduced.
Comparative examples 6 to 7
The pressure-sensitive adhesive is P2, and flame retardants with different amounts are added on the basis of the P2 pressure-sensitive adhesive, so that the flame retardance is improved along with the addition amount of the flame retardants, but the performance of the pressure-sensitive adhesive is obviously reduced. In addition, the phosphorus-containing monomer is singly introduced, and the polymerization product has a large amount of residual monomer due to insufficient molecular weight, so that the pressure-sensitive adhesive performance is reduced.
Examples 5 to 12
The pressure-sensitive adhesive used in examples 5 and 6 is P3, the pressure-sensitive adhesive used in examples 7 and 8 is P4, the pressure-sensitive adhesive used in examples 9 and 10 is P5, the pressure-sensitive adhesive used in examples 11 and 12 is P6, and different amounts or types of flame retardants, curing agents, tackifying resins and the like are added on the basis of the P3-P6 pressure-sensitive adhesive.
Comparison of the data of example 9 with comparative example 4 and comparative example 5 shows that the phosphorus-containing monomer and cyclic monomer grafted modified acrylate pressure-sensitive adhesive can prepare pressure-sensitive adhesive with better pressure-sensitive property and flame retardance at a lower flame retardant addition amount than the acrylate pressure-sensitive adhesive without grafted phosphorus-containing monomer.
Comparison of the data of example 9 and comparative example 7 shows that the phosphorus-containing monomer and cyclic monomer grafted modified acrylate pressure-sensitive adhesive is capable of preparing pressure-sensitive adhesives with better high temperature retention and flame retardance at lower flame retardant addition than the acrylate pressure-sensitive adhesive grafted with phosphorus-containing monomer alone.
In examples 11 and 12, the flame-retardant pressure-sensitive adhesive with excellent flame-retardant performance and pressure-sensitive performance can be obtained by grafting and modifying the acrylic pressure-sensitive adhesive with different phosphorus-containing monomers and cyclic monomers and matching with different flame retardants.
According to the invention, through a graft copolymerization process, the phosphorus-containing monomer and the cyclic monomer are simultaneously introduced to modify the acrylic acid ester pressure-sensitive adhesive, the dosage of the phosphorus-containing monomer and the conversion rate of the polymerized monomer are obviously improved under the condition of obtaining higher molecular weight, and meanwhile, excellent pressure-sensitive performance and good basic flame-retardant effect are obtained, so that the gelatin adhesive not only meets the general technical requirements (such as high stripping force, high shearing force, high heat resistance and the like) of the pressure-sensitive adhesive product of the power battery, but also has excellent flame retardance, so that the power battery can cope with more complex use environments, and the safety and reliability of the power battery are improved.
